I just posted a patch to org-exp-blocks.el that fixes a small typo/bug.
After that patch is applied, the code below[1] can be used to add a new
block type which will automatically process blocks with dot then eps.
For example the following block specification will create out-w-eps.eps
and org-w-eps.pdf files on export.
#+begin_dot-and-eps out-w-eps
digraph test {
a -> { b c d e };
e -> { f g h i };
};
#+end_dot-and-eps
